Description

Technical Field

[0001] This invention relates to the field of umbrella manufacturing technology, and more specifically to a circumferentially oriented feeding device for umbrella tubes. Background Technology

[0002] The umbrella tube is the core component of an umbrella, typically composed of multiple interconnected tubular sections. One end of the tube is the connecting end, and the other end is a positioning end with an anti-rotation plane on its side. This anti-rotation plane must precisely align with the mating parts to allow the umbrella ribs to open and close properly. During umbrella assembly, the umbrella tube needs to be manually rotated to bring the anti-rotation plane to its designated position for matching the mating parts. Therefore, axial adjustment of the umbrella tube's assembly position is necessary.

[0003] As shown in the prior art disclosed in CN106081588B, although the prior art includes: a base with a storage bin and a feeding channel whose upper end is connected to the lower end of the storage bin; the umbrella tube circumferential directional feeding device further includes: a tube feeding mechanism located below the feeding channel, a tube gripping mechanism located on one side of the tube feeding mechanism, an axial positioning mechanism located behind the tube gripping mechanism, and a circumferential directional mechanism located on the other side of the tube feeding mechanism and opposite to the tube gripping mechanism. However, when the number of umbrella tubes in the storage bin is insufficient, the prior art cannot replenish the umbrella tubes in the storage bin in real time, which will affect the feeding efficiency of the umbrella tubes. Summary of the Invention

[0004] To overcome the aforementioned deficiencies of the prior art, the present invention provides a circumferentially oriented umbrella tube feeding device. A drive motor drives a first synchronous pulley, which in turn drives a second and third synchronous pulley via a synchronous belt. This allows multiple material plates on the synchronous belt to reciprocate from top to bottom, moving the umbrella tubes within the feeding bin and ensuring orderly feeding and conveying. It also allows subsequent umbrella tubes to be placed orderly between adjacent material plates and then conveyed into the feeding bin via the synchronous belt. This achieves orderly umbrella tube conveying and allows for real-time replenishment of the umbrella tube storage in the feeding bin, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a circumferential directional feeding device for umbrella tubes, comprising a feeding bin, wherein an assembly hole is provided on the front side of the feeding bin, and a replenishing component for orderly feeding is provided inside the assembly hole; The feeding component includes a second synchronous pulley located behind the first synchronous pulley, and a third synchronous pulley located on the top of the second synchronous pulley. The first synchronous pulley, the second synchronous pulley, and the third synchronous pulley are arranged in a triangular pattern. The second synchronous pulley and the third synchronous pulley are both movably connected to the assembly hole through a rotating shaft. The first, second, and third synchronous pulleys are driven by a synchronous belt, and multiple spaced material plates are installed on the outside of the synchronous belt.

[0006] In a preferred embodiment, the bottom of the feeding hopper is provided with two support plates, and a belt conveyor is installed between the two support plates. A servo motor for driving the belt conveyor is installed on the outside of one of the support plates, and both ends of the first synchronous pulley are movably connected to the two support plates respectively through rotating shafts. A drive motor is installed on the side of the support plate corresponding to the first synchronous pulley, and the output shaft of the drive motor passes through the support plate and is fixed together with the rotating shaft on the first synchronous pulley.

[0007] In a preferred embodiment, the belt conveyor is provided with a plurality of spaced material platforms, the feeding bin is located on top of one of the material platforms, the material platform has a material trough on the side near the belt conveyor, and the material platform has a plurality of material holes connected to the material trough on its exterior.

[0008] In a preferred embodiment, the belt conveyor has a housing inside, with two support plates fixed to each end of the housing. An air hole is provided on the top of the housing, and the air hole corresponds vertically to the position of one of the material troughs. A vacuum pump is installed on the side of one of the support plates away from the belt conveyor, and the output end of the vacuum pump passes through the support plate and is fixedly connected to the housing.

[0009] In a preferred embodiment, a telescopic rod is installed on the top of one of the support plates near the belt conveyor via a bearing. The telescopic rod is positioned to correspond left and right to the feed bin. An axial clamping plate is installed at the end of the telescopic rod near the feed bin. An electromagnetic ring is installed on the side of the support plate near the telescopic rod. A spring is installed on the side of the electromagnetic ring near the axial clamping plate. A connecting ring is installed on the side of the spring away from the electromagnetic ring. The end of the connecting ring away from the spring is movably connected to the axial clamping plate through a bearing.

It can also orderly place the subsequent umbrella tubes between two adjacent material plates and then convey them into the feeding bin through the synchronous belt. This achieves the orderly conveying of umbrella tubes and can replenish the umbrella tube storage in the feeding bin in real time. 2. By drawing air with a vacuum pump to create negative pressure, the umbrella tubes falling onto the material platform can be adsorbed by the negative pressure, ensuring the stability of the umbrella tubes when axially positioned. After the material platform is separated from the box, the air pressure at the material platform returns to normal, making it easy to pick up the umbrella tubes after axial adjustment. In addition, the orderly conveying of the belt conveyor can realize material picking without stopping the machine, thereby effectively improving the material feeding efficiency of the umbrella tubes.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Refer to the instruction manual appendix Figure 1-7 This invention provides a circumferential directional feeding device for umbrella tubes, including a feeding bin 1. An assembly hole 2 is provided on the front side of the feeding bin 1, and a feeding component for orderly feeding is provided inside the assembly hole 2. The feeding component includes a second synchronous pulley 4 located behind a first synchronous pulley 3, and a third synchronous pulley 5 located on top of the second synchronous pulley 4. The first synchronous pulley 3, the second synchronous pulley 4, and the third synchronous pulley 5 are arranged in a triangular pattern. The second synchronous pulley 4 and the third synchronous pulley 5 are both movably connected inside the assembly hole 2 via rotating shafts. The first synchronous pulley 3, the second synchronous pulley 4, and the third synchronous pulley 5 are driven by a synchronous belt 6, and multiple spaced material plates 7 are installed on the outside of the synchronous belt 6.

[0019] To ensure the stability of the feeding hopper 1 during material feeding, two support plates 8 are provided at the bottom of the feeding hopper 1, and a belt conveyor 9 is installed between the two support plates 8. A servo motor 10 for driving the belt conveyor 9 is installed on the outside of one of the support plates 8, and both ends of the first synchronous pulley 3 are movably connected to the two support plates 8 through rotating shafts. A drive motor 11 is installed on the side of the support plate 8 corresponding to the first synchronous pulley 3. The output shaft of the drive motor 11 passes through the support plate 8 and is fixed together with the rotating shaft on the first synchronous pulley 3. In this way, the drive motor 11 can be started, and the drive motor 11 drives the first synchronous pulley 3 to rotate. The first synchronous pulley 3 drives the second synchronous pulley 4 and the third synchronous pulley 5 through the synchronous belt 6. In this way, the umbrella tubes in the feeding hopper 1 can be reciprocated from top to bottom by multiple material plates 7 on the synchronous belt 6, ensuring the orderly feeding of the umbrella tubes. Furthermore, the staff can orderly place the subsequent umbrella tubes between two adjacent material plates 7, and then transport them to the inside of the feeding bin 1 by the synchronous belt 6, thereby realizing the orderly transportation of umbrella tubes and replenishing the umbrella tube storage in the feeding bin 1 in real time.

[0020] When the umbrella tubes in the feeding bin 1 are conveyed down to the belt conveyor 9 by the synchronous belt 6, to ensure the stability of the umbrella tubes during conveying, multiple spaced material platforms 12 are embedded outside the belt conveyor 9. The feeding bin 1 is located on top of one of the material platforms 12. A material trough 13 is opened on the side of the material platform 12 closest to the belt conveyor 9, and multiple material holes 14 connected to the material trough 13 are opened on the outside of the material platform 12. The belt conveyor 9 has a housing 15 inside. The two ends of the housing 15 are fixed to two support plates 8 respectively, and an air hole 17 is opened on the top of the housing 15. The air hole 17 corresponds vertically to one of the material troughs 13. A vacuum pump 16 is installed on the side of one of the support plates 8 away from the belt conveyor 9, and the output end of the vacuum pump 16 passes through the support plate 8 and is fixedly connected to the housing 15. In this way, the vacuum pump 16 can be started to draw in air and create negative pressure. Because the material hole 14 in the material platform 12 is connected to the air hole 17 on the box 15, the vacuum pump 16 can draw air from the material platform 12, which facilitates the adsorption of the umbrella tube falling on the material platform 12 by using negative pressure, thereby ensuring the stability of the umbrella tube when it is axially positioned.

[0021] After the umbrella tube is fixed, its axial direction needs to be adjusted. Therefore, a telescopic rod 18, connected by a bearing, is installed on the top of one of the support plates 8 near the belt conveyor 9. The telescopic rod 18 corresponds left-right to the position of the feeding bin 1. An axial clamping plate 19 is installed at the end of the telescopic rod 18 near the feeding bin 1. An electromagnetic ring 20 is installed on the side of the support plate 8 near the telescopic rod 18. A spring 21 is installed on the side of the electromagnetic ring 20 near the axial clamping plate 19. A connecting ring 22 is installed on the side of the spring 21 away from the electromagnetic ring 20. The end of the connecting ring 22 away from the spring 21 is movably connected to the axial clamping plate 19 via a bearing. A motor 23 for driving the telescopic rod 18 to rotate is installed outside the support plate 8. A pressure plate 24 is installed on the top of the other support plate 8 near the belt conveyor 9. The pressure plate 24 is located on top of the belt conveyor 9. In this way, the pressure plate 24 can press and limit one end of the umbrella tube falling onto the material table 12, preventing the umbrella tube from tilting or shifting, and ensuring the stability of the umbrella tube when it is axially adjusted.

[0022] Before the umbrella tube falls to the material platform 12, the staff turns on the electromagnetic ring 20. The electromagnetic ring 20 attracts the spring 21, and the spring 21 generates a magnetic field and gradually contracts, thereby causing the spring 21 to drive the axial clamping plate 19 to move outward, so as to prevent the axial clamping plate 19 from obstructing the fall of the umbrella tube.

[0023] After the umbrella tube falls onto the material platform 12, the operator disconnects the power supply to the electromagnetic ring 20. The magnetic field of the spring 21 disappears, allowing the axial clamping plate 19 to gradually contact the umbrella tube with the help of the spring's rebound force. Simultaneously, the motor 23 drives the telescopic rod 18 to rotate, which in turn rotates the axial clamping plate 19, allowing it to gradually engage with the umbrella tube during rotation. After engaging with the umbrella tube, the axial clamping plate 19 is then driven to rotate the umbrella tube, achieving axial adjustment of the umbrella tube.

[0024] After the umbrella tubes are axially adjusted, the belt conveyor 9 is driven by the servo motor 10 to transport the umbrella tubes in an orderly manner. After the material platform 12 separates from the box 15, the air pressure at the material platform 12 returns to normal, making it easier for subsequent equipment to pick up the axially adjusted umbrella tubes. Moreover, the orderly transport of the belt conveyor 9 can achieve non-stop transport, which can effectively improve the feeding efficiency of the umbrella tubes.

[0025] To ensure the stability of the feeding hopper 1, support frames 25 are installed on both sides of the top of the feeding hopper 1, and the bottom of the support frame 25 is fixed to the top of the support plate 8. In this way, the two support frames 25 can limit the two ends of the feeding hopper 1, ensuring the stability of the feeding hopper 1 and preventing the feeding hopper 1 from tilting or shaking.

[0026] In order to promptly understand the amount of umbrella tubes stored in the supply bin 1, through holes 26 are provided on both sides of the supply bin 1, and transparent viewing panels 27 are installed inside the through holes 26. In this way, the contents of the supply bin 1 can be observed from the outside with the help of the transparent viewing panels 27, thus facilitating timely understanding of the amount of umbrella tubes stored in the supply bin 1.

[0027] To ensure the cleanliness of the material platform 12, a fixing plate 28 is provided at the bottom of the rear end of the belt conveyor 9. The two ends of the fixing plate 28 are respectively fixed to two support plates 8, and a soft brush 29 for cleaning the material platform 12 is installed on the top of the support plate 8. In this way, the soft brush 29 can repeatedly contact the material platform 12 during the reciprocating operation of the belt conveyor 9, which facilitates the cleaning of the material platform 12, prevents debris from adhering to the outside of the material platform 12, and ensures that the surface of the material platform 12 is clean.

[0028] In conclusion, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
